I set up drbd on 2 nodes, they used to connect to each other at once
on startup, but after a computer crash, they take forever to
synchronize! Here's what I got from my primary node when I did a "cat
/proc/drbd".

Hi,
i have two identical servers equipped with 10 GigE cards. MTU is set to 9000
and with iperf i got over 9 Gbit/s over my network connection. The servers are
directly connected. The disks (10x 2 TB SATA, RAID 6) are quite fast. I got
about 700 MB/s write speed with drbd standalone. With drbd
Tyler,
You're using a default RPM configuration, which sets the RPM paths
somewhere below /usr/src/redhat, which you most likely don't have write
permission for.
Set up a build hierarchy in your home directory, and set your paths in
your ~/.rpmmacros file properly.
And "rpmbuild -tb", and thus m

That
approach is working perfectly, except for one set of boxes that have
with exactly same hardware configuration. And I just want to figure out
why it is behaving in this manner on thes
Hi,
I did a new install of CentOS 5.4 on an HP DL360 G5 server and updated
all packages to the newest versions. The kernel is
2.6.18-164.6.1.el5PAE.
I successfully built and installed DRBD 8.3.6 from source using these
commands:
wget http://oss.linbit.com/drbd/8.3/drbd-8.3.6.tar.gz
tar zxvf drbd

Hello,
I'm wondering if there drbd supports a configuration of two nodes with
each two nic's in two separate lan's.
eg
- node 1 connected to lan x and lan y
- node 2 connected to lan x and lan y
The drbd syncs through both lan-s or fails over from lan x to lan y when
lan x fails.

Jero

Hello,
Please pardon any mistakes, as I am relatively new to DRBD.
I've recently started to use DRBD to synchronize a 2TB volume over a
low-speed (10-14 megabit) wireless link to an offsite location. I
initialized the original volume using ocfs2 and drbd and copied to the
second volume using dd,
